Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispensing cap, and more particularly, to an improvement of a dispensing cap in which a cover plate is hinged so as to be freely opened and closed by an inverted hinge mechanism.

[0002]

2. Description of the Related Art As a dispensing cap, a rear upper end of a cap base and a rear lower end of a lid are connected by a pair of hinges provided at a predetermined interval. An elastic plate in the shape of an inverted L-shaped plate is provided at the rear center of the lid top wall via a hinge, and the lower end is connected at the rear center of the cap base peripheral wall via a hinge. 2. Description of the Related Art There is known a so-called three-point hinge having a reversible hinge mechanism connected so as to be elastically reversible. In addition, these caps are configured such that a plug projection vertically provided from the back surface of the lid top wall is removably fitted to an injection tube formed in the top wall of the cap base, and a finger hook projection provided on the front surface of the cap. The cover is opened by pushing up.

[0003]

When the cap is opened or closed to a predetermined position, the cap is automatically opened or closed by the action of a reversing hinge mechanism, and the closed state or the open state is stabilized. While being able to maintain and handle conveniently,
It is an excellent product that can be manufactured at low cost because it can be formed by integral molding of synthetic resin, but the plug projection is generally configured to fit tightly into the dispensing cylinder in order to maintain good liquid tightness. , A relatively large force is required initially when the lid is opened, because in addition to the urging force in the closing direction of the elastic plate up to the reversal boundary position at the time of opening the lid, a force is required when the plug projection comes off from the dispensing cylinder. .

[0004] Generally, the finger-hung projection of this type of cap has a small projection width due to the reason that the appearance of the cap is improved or that a normal capper can be used at the time of liquid filling so that the cap can be placed on an existing filling line. Due to the configuration, there is a disadvantage that it is difficult to open relatively easily. In addition, when opening the lid, the reversing hinge mechanism does not act in the opening direction unless the lid is opened to a position having a relatively wide opening angle. Difficult to open body.

The present invention has been made in view of the above points, and in this kind of cap, the lid can be easily opened with only one hand holding the container, and even if the container is accidentally turned down. An object of the present invention is to provide an excellent pouring cap which does not cause a disadvantage that the lid is opened and the contents liquid leaks.

[0006]

In order to solve the above-mentioned problem, the cap according to the present invention is a stopper that is closely fitted to the cap base 2 on which the discharge tube 11 is erected from the top wall 8 so as to be detachable from the discharge tube 11. Protrusion 18
Of the lid 3 suspended from the top wall 17 with the reversing hinge mechanism 4
In the pouring cap hinged so as to be openable and closable, a concave portion 9 having an upper surface opening is provided on the front surface of the cap base 2, and a front end portion is communicated with the upper end of the concave portion 9 so that the central portion of the base top wall is rearward. An extending groove 10 is formed, and the upper surface of the recess 9 and the groove 10 is covered and fixed to the cap base top wall 8 while the base is opened in the groove 10. The front end of the sliding plate portion 24 is provided with a more protruding closed top plate 6, and the pouring cylinder 11 is loosely fitted in the central elongated hole 23 and slides on the upper surface of the base 2 at the lower portion inside the concave groove 10. And a push button 5 having a rear end of the sliding plate 24 bent and protruded to a position where the rear end of the slide plate 24 can come into contact with the back surface of the hinge mechanism 4. Forming the closed top plate 6 above the pressing protrusion 26 protruding from the upper surface on the swingable swing plate portion 15 and pressing the front surface of the push button 5 When the swing plate portion 24 is further retracted, the front portion of the lid is pushed up by the pressing projection 26 via the swing plate portion 15, and the rear surface of the reversing hinge mechanism 4 is pressed by the rear end of the slide plate portion 24 to open the lid. It was configured as follows.

[0007]

When the front surface of the pressing plate portion 25 of the push button 5 is pressed at the time of opening the lid, the sliding plate portion 24 retreats integrally, and the pressing protrusion 26 pushes up the protrusion 27 of the swing plate portion 15, and By pushing up the lid 3 in conjunction therewith, the plug projection 18 which requires a relatively large force at the beginning of opening can be easily separated from the pouring cylinder 11 and the reversing hinge mechanism 4 is provided at the rear end of the sliding plate 24. Is pushed up to the lid opening position of the reversing hinge mechanism 4 (that is, the lid opening angle at which a force acts in a direction to return to the original state after being elastically deformed in a direction in which the inverted L-shaped elastic plate spreads). Because it is possible, the lid can be easily opened with only one hand holding the container.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 6 show an embodiment of the present invention. In the drawings, reference numeral 1 denotes a pouring cap. The cap 1 has a cap base 2 and a lid 3 integrally formed via a reversing hinge mechanism 4, and also has a push button 5 for opening the lid and a closure for slidably fixing the button 5. A top plate 6 is provided.

The cap base 2 has a top wall 8 from an upper end of the peripheral wall 7.
Is formed in a rectangular cylindrical shape with an opening at the lower end surface, and a concave portion 9 having an upper end opened at the front surface of the peripheral wall 7. A recess 10 extending in the form of a strip extending rearward through the front end of the recess 9 is formed on the upper surface of the top wall 8, and the rear end face of the recess 10 is formed as a curved surface 10a which rises rearward. In addition, a short cylindrical pouring cylinder 11 having a base end opened in a concave groove 10 substantially at the center of the top wall 8, and is screwed to the mouth and neck of a container body to be mounted at the center of the back surface of the top wall 8. A threaded tube portion 12 is provided to allow the screw tube portion 12 to suspend.

A closed top plate 6 is fixed to the upper surface of the base 2 by an appropriate fixing means such as fusion. The closed top plate 6 has a flat rectangular shape in which both lower surfaces are fixed to the upper surface of the base top wall 8 on both sides of the concave groove 10 and a pouring cylinder 11 protrudes from the center. The end is open. Also,
At the center of the front end portion, a parallel cut groove 13 is formed, and a thin hinge 14 is provided between each cut groove 13 to form a rocking plate portion 15 which is configured to be rockable. As shown in FIG. 7, the closed top plate 6 forms a thin hinge 14A which crosses a predetermined position of the front portion, and a swing plate portion 15A which can swing the entire front end.
May be used.

The lid 3 has a top wall 17 extending from an upper edge of a rectangular cylindrical peripheral wall 16 having a lower edge abutting on a peripheral edge of the upper surface of the closed top plate 6. A plug projection 18 that fits into the outlet cylinder 11 is projected.

The reversing hinge mechanism 4 connects the upper rear end of the cap base 2 and the lower rear end of the lid 3 with a pair of hinges 19 provided at a predetermined interval.
An inverted L formed between the upper and lower walls of the cap base peripheral wall 7 via a hinge 21 and having an upper end connected to a rear center of the lid top wall 17 via a hinge 20.
This is a well-known mechanism provided with an elastic plate 22 in the shape of a letter plate, and is integrally formed.

Further, the push button 5 has a long hole 23 formed at the center for the escape of the pouring tube 11 and is slidably mounted in the concave groove 10 of the cap base 2 so as to be slidable back and forth. Sliding plate 24
And a pressing plate portion 25 is vertically provided from a front end edge of the plate portion 24 to a front end portion in the recess 9. At the front end of the upper surface of the sliding plate portion 24, a pressing projection 26 having an inclined surface 26a that becomes lower toward the trailing edge side is formed. A projection 27 having an inclined surface 27a in contact with the inclined surface 26a is provided at

The rear edge of the sliding plate portion 24 is curved upward along the curved surface 10a of the concave groove 10 so as to protrude from the opening, and is located in the vicinity of the back surface of the reversing hinge mechanism 4. When the moving plate portion 24 retreats, the moving plate portion 24 comes into contact with the back surface of the reversing hinge mechanism 4 and is pressed.

The above members are all formed of a synthetic resin. In particular, the push button 5 is preferably formed of a relatively flexible resin.

[0017]

[Effect of the Invention] As described above, the cap of the present invention pushes up the swinging plate portion 15 with the pressing protrusion 26 when the sliding plate portion 24 retreats by pressing the front surface of the push button.
Since the front part of the lid 3 is pushed up, and the rear surface of the reversing hinge mechanism 4 is pressed by the rear end of the sliding plate part 15 to open the lid, the pressing force of the push button 5 is small, and the push button 5 Can be pushed backward from the front of the cap base 2, so that the lid can be easily opened with only one hand holding the container.

The front end of the push button 5 is provided on the cap base 2.
Because it protrudes into the recess 9 on the front face so that it can be pushed in,
Even if the container is accidentally overturned, there is no fear that the lid is opened and the contents liquid leaks.

Further, the upper surface of the concave portion 9 and the concave groove 10 is covered and fixed to the cap base top wall 8, and a pouring cylinder 11 having a base end opened in the concave groove 10 is protruded from the center. Since the closed top plate 6 is provided, even if there is liquid dripping along the outer surface of the pouring cylinder, the liquid is prevented from reaching the sliding portion of the sliding plate as much as possible, and as a result, the push button slides. It also has the advantage that inconvenience such as causing a defect can be prevented as much as possible.
